Sizes of Windows integral types

While developing WinSafe, it’s very common to convert the Windows integral data types to their Rust equivalent. Care must be taken, however, when it comes to pointer size, which varies according to the architecture. Since WinSafe is aimed to both 32 and 64-bit Windows, I must pay attention.

For reference, below is the table I’m using to figure out the sizes:

Signed C	Signed Rust	Unsigned C	Unsigned Rust	32-bit	64-bit
CHAR	i8	UCHAR BYTE BOOLEAN	u8	8 bit (1 byte)
SHORT	i16	USHORT WCHAR WORD	u16	16 bit (2 byte)
BOOL INT LONG	i32	UINT ULONG DWORD	u32	32 bit (4 byte)
INT_PTR LONG_PTR LPARAM	isize	UINT_PTR ULONG_PTR WPARAM SIZE_T	usize	32 bit (4 byte)	64 bit (8 byte)
LARGE_INTEGER LONG64 LONGLONG	i64	ULARGE_INTEGER ULONG64 ULONGLONG DWORD64 DWORDLONG QWORD	u64	64 bit (8 byte)

The table above is an extension of this one.
